Can someone suggest, whether there is any information regarding the staring time of recording for EEG /fMRI data for the dataset ds000116 on openfmri.
For example in the file

behavdata.txt

the timestamps start from

TrialOnset Response Stimulus RT
6.728 0 standard NaN

I am asking whether they started to record the EEG and fMRI from beginning of time i.e. 0 sec. Does that mean the subject was resting in the MRI scanner for first 6+ seconds, and was not shown any stimulus(standard/target). They also mention in their paper that fMRI was recorded each 2s. Did they recorder first fmri image at 0s and then continue recording till end?
